During the 12-vear survey, counts were done counts at 11 years (7.4 x 10* in the exposed and 7.3 X 10° in the unexposed). Differential counts showed neutrophils and lymphocytes to have very nearly the same meanlevel for exposed and unexposed Rongelapese at 11 years. Graphic treatmentof these elementsis presented in Figures 49 through 54. Thesimilarity of counts between the two groupsis probably best seen in the cumulative percentdistribution curves (Figure 55). The levels of eosinophils, monocytes, and basophils were not remarkably different between the exposed and unexposed groups and were similar to the levels in past surveys. variability in counts.
